Title: Improvements in and relating to apparatus for operating coke oven doors and the like
IPC: C10B25/14
Filed: 1925-06-02
Abstract: 250,053. Wellman, Smith, Owen, Engineering Corporation, Ltd., (Wellman-Scaver-Morgan Co.). June 2, 1925. Coke ovens.-Apparatus for shifting coke oven &c. doors of the kind adapted to travel along the front of a battery comprises a door lifting member which by a single operation engages the door, tilts it outwards from its casing and then lifts it off the sill so that the .door carrying member may be backed away from the opening. The extractor mechanism is mounted on a carriage 9 travelling on a track extending along the front of the ovens and is carried hy a ram 10 movable transversely by a rack and pinion 11, 12. A housing 13 secured to the ram 10 has a projecting portion 14 from which is suspended by a link 17 a casting 16 having projecting arms 18, 19 engaging the door below the brackets 3, 4, the lower arms projecting further than the upper arms due to the pressure of springs 20 which hold the lower end of the casting outwardly. When the ram 10 is moved forwardly the arms 19 first engage the door compressing the springs 20 and causing the upper end of the casting 16 to swing forward and bring the arms 18 into contact with the door. On operation of the motor 38 a horizontal screw 36 is rotated, causing a nut 35 to travel along the screw and actuate lever 33 and the arms 31, 29 of a bell crank lever mounted on an extension 27 of the casting 16 so that a hook 30 engages the rod 7, and, by a rod 39 connecting an arm 40, a hook 41 engages the rod 8. Continued movement of the lever 33 causes an upward thrust to be exerted on the door, but as the casting 16 is movable the upward movement of the arms 29 ceases while the bell crank lever and the upper end of the casting are moved outwardly until the casting meets an abutment 42 pulling the upper end of the door outwardly. As soon as the outward movement is arrested continued movement of the lever 33 causes further movement of the bell crank lever about its pivot so that the weight of the door is taken from its sill and the ram may be moved away from the opening carrying the door with it. In replacing the door the movements described above take place in the reverse order.

Abstract: 311,940. Blancafort, A. May 16, 1928. Moving-map and like indicators for vehicles.- In a route-progress indicator for vehicles the complete itinerary is exposed to view on a strip 8 secured to a box and having a slot 12 through which projects the indicator pointer 42. The latter is carried by a finger 41 secured to a chain 35 which runs round sprocket gears 36 at opposite ends of the box and also round opposite sides of two sprocket gears 33, 34, the shafts of which form part of a rocking yoke-member 22 which can be moved so as to bring either of two sprocket wheels 19, 20 into engagement with one of two oppositely-threaded worms 17, 18 secured to a shaft positively rotated by a wheel of the vehicle. By this means the travel of the pointer 42 may be reversed at any moment. The pointer is set by moving the yoke 22 into the neutral position and turning a finger-wheel secured to one of the sprocket gears 36.

Electricity, supplying by meter.-A coin drum 1 moves a lever 6 to which is pivoted a lever 7 carrying a pin 8, which engages under a rim 4 on a disc which is moved by the setting mechanism of the meter. The movement of lever 6 causes a pin 11 to engage and lift the contact 12, and also causes a pin 14 to rotate a catch 16 which in turn moves a lever 20 so that a pin 19 engages the contact 18 and moves it in the same direction as the contact 12. When the pin 14 moves past the catch 16, the latter frees the lever 20, allows the contact 18 to close the switch, and holds the switch closed. When the quantity paid for has been delivered, the gap 9 releases the pin 8 and the switch opens under the action of spring 12 or of a spring embodied in the mechanism. The switch is applicable to prepayment meters of the type described in Specification 1363/14.

Title: Medicinal preparation and process of producing same
IPC: A61K31/295
Filed: 1932-05-24
Abstract: Solutions of iron-copper protein compounds such as iron nucleinate or peptonate and and copper nucleinate or caseinate are stabilized by the addition of water-soluble fruit acid salts such as sodium citrate.  Copper nucleinate is prepared from yeast by treatment with dilute sodium hydroxide, partial neutralization with hydrochloric acid followed by acidification with acetic acid. The solid matter is allowed to settle and the liquid filtered, copper sulphate is added and stirred till dissolved and the flocculent precipitate allowed to settle, filtered and washed till free from sulphates.  The precipitate is then washed with alcohol and ether and dried.  In preparing iron nucleinate from yeast a similar procedure is followed, ferric chloride being the source of iron, while the precipitation is effected in 60 per cent alcohol. A copper nucleinate is obtained from nucleic acid by a similar process in which the percentage of copper is considerably less than that in that obtained from yeast.  Copper caseinate is obtained by the addition of a solution of copper sulphate to a solution of casein in dilute sodium hydroxide, filtration and washing with alcohol and ether.  Alcohol, glycerine, sugar and flavouring substances (oil of orange, ethyl acetate, vanillin) are added to the mixture for therapeutic use.ALSO:Solutions of iron-copper protein compounds such as iron nucleinate or peptonate and copper nucleinate or caseinate are stabilized by the addition of water soluble fruit acid salts such as sodium citrate.

The Specification describes methods of preparing the metal protein compounds which are employed in such proportions that the mixture contains about twice as much iron as copper.

Abstract: 908,996. Magnetic recording &c. heads. MINNESOTA MINING & MANUFACTURING CO. May 1, 1959 [May 5, 1958], No. 14993/59. Class 40 (2). A magnetic head for high-frequency use generates a magnetic field across the gap of a tubular conductive ferro-magnetic core member by passing an axial current through the core itself. A multi-track head, Fig. 2, has U-form conductors 3, looped through a transformer core 13 and connected to the core 1 at spaced points on the axis defining the head width. The shape of the conductors is designed to achieve a uniform current distribution. Cross-talk between adjacent heads sharing the core 1 is reduced by ferro-magnetic members 17 fitted to the core to bridge its gap between adjacent conductors 3, each of which has an independent transformer. A head for scanning a record transversely to its relative motion has a core 31 which is also magnetostrictive and which is stressed by means 49 such as to reduce its circumferential permeability nearly to unity. Pulses generated by the piezo-crystal 39 follow one another down the core and are of such polarity as to restore the circumferential permeability as the pulse passes, producing the " virtual gap " effect described in Specification 908,707. The circuit is completed by the members 33, 35, 43 and 51 is the coupling transformer.

Telegraph and telephone apparatus.-In coinactuated mechanism in which, on the insertion of a coin or the like, reception from a wireless-receiving apparatus is obtained for a predetermined time, means are provided to permit the user to interrupt reception, as described, during the predetermined time interval. As applied to the apparatus described in Specification 317,886, a hook 26 is provided on the end of one arm 27 of a bell-crank lever 27, 29, the other arm 29 of which engages stop 30 on the sliding switch actuating rod 18. When the hook 26 is depressed against the action of a spring 32 by the finger of the user or by hanging earphones thereon, the rod 18 is moved to open the switch controlling the high and low tension circuits, and the clock is stopped. When the hook is released, the resilience of the switch contacts moves the rod 18 back to restart the clock. Reception may be interrupted, as desired, the total operative period of the clockwork being the same as if it were running continuously. The hook mechanism may be arranged to act on the switch contacts directly.
